Decametric radio observation from Nancay decameter array. The Nancay Decameter Array (NDA) at the Station de Radioastronomie de Nancay (SRN) is a phased array of 144 "Teepee"...

This database is a collection of maps created from the 28 SAS-2 observation files. The original observation files can be accessed within BROWSE by changing to the SAS2RAW...

Numerous studies have reported significant displacements in the coordinates of active galactic nuclei (AGN) between measurements using the Very Long Baseline Interferometry...

Open clusters that emerged from the star forming regions as gravitationally bound structures are subjected to star evaporation, ejection, and tidal forces throughout the rest of...

The IPCIMAGE database contains information from the Imaging Proportional Counter aboard HEAO 2, the Einstein Observatory. Einstein incorporated a high-resolution X-ray telescope...

The HRIIMAGE database table contains information from the High Resolution Imager aboard HEAO 2, the Einstein Observatory. Einstein incorporated a high-resolution X-ray telescope...

The European Space Agency's satellite COS-B was dedicated to gamma-ray astronomy in the energy range 50 MeV to 5 Gev and carried a single spark chamber telescope with...

This database table contains the images from two EXOSAT LE telescopes with the channel multiplier array (CMA) detectors in the focal plane. The CMA/telescope combination covers...

We applied the revised M subdwarf classification criteria discussed in Zhang+ 2019, J/ApJS/240/31 (Paper I) to Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)...

Measurements of the obliquities in exoplanet systems have revealed some remarkable architectures, some of which are very different from the Solar System. Nearly 200 obliquity...

K2-24 is a planetary system composed of two transiting low-density Neptunians locked in an almost perfect 2:1 resonance and showing large TTVs, i.e., an excellent laboratory to...

We aim to constrain the chemo-dynamical properties of the Sagittarius (Sgr) dwarf galaxy using carbon abundances. At low metallicities in particular, these properties reveal the...

The Baade-Wesselink method, also known as the pulsation parallax method allows us to estimate distances to individual pulsating stars. Accurate geometric parallaxes obtained by...

The Northern HIPASS catalogue (NHICAT) is the northern extension of the HIPASS catalogue, HICAT. This extension adds the sky area between the declination (Dec.) range of...

We present a homogeneous compilation of HI spectral parameters extracted from global 21cm line spectra for some 9000 galaxies in the local universe (heliocentric velocity...

The HI Parkes All-Sky Survey (HIPASS) Catalogue forms the largest uniform catalogue of HI sources compiled to date, with 4315 sources identified purely by their HI content. The...

The catalog contains a list of redshifts for Zwicky's Near Clusters. All of the 503 Zwicky Near Clusters as given in the Uppsala General Catalogue of Galaxies (UGC) are listed...

The catalog contains machine-readable versions of the "Catalog of CO Radial Velocities Toward Galactic HII Regions" (Blitz et al. 1982) and the "Catalog of Carbon Monoxide...

In the framework of the Standard Model Extension (SME), we present improved constraints on anisotropic Lorentz invariance and Charge-Parity-Time (CPT) violation by searching for...

We have assembled 560 recent measurements from the literature of distances of Galactic globular clusters and found revised distance estimates for 154 of the 157 clusters in the...
